Matsya Purana — Paurava Genealogy
क्षत्रस्य याजिनः केचिच् छापात्तस्य महात्मनः पौर्णमासेन हविषा इष्ट्वा तस्मिन्प्रजापतिम् स वैशम्पायनेनैव प्रविशन्वारितस्ततः //
kṣatrasya yājinaḥ kecic chāpāttasya mahātmanaḥ paurṇamāsena haviṣā iṣṭvā tasminprajāpatim sa vaiśampāyanenaiva praviśanvāritastataḥ //
Some performers of sacrifice, through a curse aimed at that great-souled Kṣatriya sacrificer—after he had worshipped Prajāpati there with the havis oblation of the full-moon Paurṇamāsa offering—then, as he was about to enter that sacred sphere, were stopped by Vaiśampāyana himself.
This verse is not about Pralaya; it focuses on ritual action (Paurṇamāsa worship of Prajāpati) and the karmic/social power of a curse that interrupts the sacrificer’s intended entry.
It highlights the Kṣatriya’s role as a yajamāna (sacrificial patron) and implies that even righteous ritual patronage can be obstructed by ethical/social breaches leading to śāpa—underscoring restraint, proper conduct with priests/sages, and dharmic accountability.
The ritual point is the Paurṇamāsa (full-moon) offering using haviṣ; it indicates a formal Vedic-style rite directed to Prajāpati, emphasizing correct timing (full moon) and proper oblation as spiritually consequential.
